NAME
    GetCurrentDirName -- returns the current directory name (V36)

SYNOPSIS
    success = GetCurrentDirName(buf, len)
    D0                          D1   D2

    BOOL GetCurrentDirName(STRPTR, LONG)

FUNCTION
    Extracts the current directory name from the CLI structure and puts it
    into the buffer.  If the buffer is too small, the name is truncated
    appropriately and a failure code returned.  If no CLI structure is
    present, a null string is returned in the buffer, and failure from
    the call (with ioerr() == error_object_wrong_type);

INPUTS
    buf     - Buffer to hold extracted name
    len     - Number of bytes of space in buffer

RESULT
    success - Success/failure indicator

    In V36, this routine didn't handle 0-length buffers correctly.
